Abstract
A method by which a terminal transmits an SRS comprises the steps of: receiving, from a base station, control information indicating a transmission request of SRS in a plurality of slots or subframes; and transmitting SRSs in the plurality of slots or subframes on the basis of the control information, wherein the control information can be received when the total number of uplink transmission beams or the number of ports for SRS transmission exceeds the maximum number of SRS beams, which can be transmitted in one slot or one subframe, or the number of ports for SRS transmission.
